1/8 mile time improvement

[I_Shoot_Back]

2003 Trailblazer.
I do have a tune in it. Truck does not want to break tires at take off(burnout) and runs 10.4 seconds in 1/8 mile.
I do have hptuners myself now,lifted the files (P10 ecu) but don't know enough about tuning to make this thing take off better
I'm having trouble finding good info on how to tune with the P10 ecu, most videos use different terms for all the tabs and seem to have more options.
Any experts on the P10 that have ideas on where to get proper info?

Has anybody studied timing curves,to where these engine like it the best?
I recorded a pull and engine ramps from 21 degrees advanced at 2500 rpm to max 30 degrees advanced at 6000 rpm.
Am I correct to think that 30 degrees is still pretty save for a NA engine?

Paging @limequat . He's our resident SME on tuning these.

However I can say that support for the P10 in HPT is limited. You can't even change the speedo calibration. I think the majority of canned tunes focuses on removing toque management and improving transmission shifts.
